Hey guys. I'm trying to connect a FT232R to a microcontroller as shown in http://www.sparkfun.com/datasheets/IC/FT232R_v104.pdf on page 26 to create a USB-UART interface. It shows a ferrite bead, and, in the datasheet, says that "the value of the Ferrite Bead depends on the total current required by the circuit – a suitable range of Ferrite Beads is available from Steward (www.steward.com) for example Steward Part # MI0805K400R-00."
The total current used by my circuit is around 90mA. I'm still not really sure how to pick out a suitable ferrite bead, though. Will this work: http://search.digikey.com/us/en/products/BKP1005HS221-T/587-2088-1-ND/1789035 ? I'm looking for something in an SMT-0402 surface mount package that will do the job.
Any info greatly appreciated. Thanks!
